Stage 1 Wake Up Kit +115 HP

The Stage 1 Wake Up Kit for 1996-2003 H1 will make a considerable difference to the overall drivability and longevity of your H1 Hummer. The basis of this performance upgrade is our unique proprietary & copyrighted RapTorq ECM. This kit instantly adds up to 115 horsepower with easy and simple installation! The Stage 1 Wake Up Kit provides exclusive, full range Dynamic Spectrum Tuning of air/fuel ratio, ignition advance, boost control, transmission and various other parameters for ultimate power gains and optimal mileage. Hands down the best performance gain available for the price!

• Power gains across entire power band, not just at full throttle
• Improves throttle response, acceleration, and low-end torque
• Provides performance gains up to 115 horsepower
• Boost Control

• Increased fuel pressure

Stage 1 – This stage is for stock or mildly modified H1 vehicles. Fuel and timing-curves are modified and programming is designed to burn lower-octanes at peak efficiency, boost control, and increased fuel pressure, resulting in improved performance and optimal mileage. Drivers can use low-cost regular octane fuel for potential mileage gains, or mid-grade and higher fuel for optimal performance gains.

**Available in Stage 1, 2, 3, & 4! Dyno tested to ensure top horsepower and drivability.

Kit Includes:

RapTorq ECM
Air Filter
Cooling Upgrade Level – 1

RapTorq High Performance ECM

Our unique proprietary & copyrighted Predator RapTorq ECM was engineered over a 22 month span with specific testing and development by our in-house Predator Motorsports engineering team.

During the development phases of our RapTorq ECM, our engineering team included a full evaluation of all available ECM programs by our competitors. While it remains standard practice to only modify the factory GM fuel-delivery curve. Our RapTorq ECM features a completely re-engineered “fuel-delivery curve &start-of-injection timing curve”. This design is engineered to optimize the H1’s combustion chamber providing peak efficiency and rapid power gains across the engines entire power band.

Our RapTorq ECM programming provides rapid throttle response from light-throttle to full heavy-throttle performance power. In conjunction with power gains, Fuel Economy is also improved on an average of 10-20% throughout all operational conditions. The primary goal was to create superior drivability with a maximum power curve within the OEM GM exhaust-gas temperature limits.

Power increased by 115hp & 156ft/lbs of torque providing Rapid Torque & Horsepower gains!

RapBoost High Performance Turbo Boost Controller

Our Predator RapBoost is a naturally suited mate to our RapTorq ECM programming or a fully stock H1 and is designed to compliment the operational characteristics of the factory turbo.

The RapBoost is a purely mechanical with a fully adjustable waste gate controller. Designed to be a direct bolt-on replacement for the OEM factory boost control canister used on H1 turbochargers.

The RapBoost works in conjunction with the factory waste gate valve mechanism to create a smooth and rapid working turbine inlet-pressure relief valve. This type of control allows retention of all available turbine drive pressure up to the predetermined pressure bypass point, providing maximum turbocharger performance along with effective shaft-speed / boost control.

Characteristic of the RapBoost design is its easy installation and simple calibration.

Power increased by 21hp & 27ft/lbs of torque providing Rapid Torque & Horsepower gains!

RapFlow High Performance Fuel Lifter

Our Predator RapFlow Fuel Lifter Pump is designed to be a direct bolt-on replacement for the low-quality factory lifter pump that is unreliable and prone to low-pressure fuel flow. The RapFlow Fuel Lifter Pump is suited perfectly for the high demands of the H1 Hummer where Rapid fuel flow, Strength, and Reliability are paramount.

The RapFlow High Performance Fuel Lifter Pumps feature a unique valve design that improves flow quantity and quality. The high-volume inlet and outlet surpasses the capacity of conventional OEM factory models. Produces 6 psi and does not require a regulator.

**We also offer a Performance Fuel Pressure Test Kit. This will determine if you are receiving adequate fuel pressure. We recommend checking fuel pressure on your stock lifter pump every 6 months or 6,000 miles.

K&N Air Filter

H1 Performance air filters from K&N will help your Hummer run better!

Designed to increase horsepower & torque for the 1996-2003 Hummer H1

Washable & Reusable

This K&N H1 air filter lasts the lifetime of your vehicle
